Yet, I'll not take on that either because you get multiple jogs and the Dasma-Tanauan being very close to Maharlika Highway and leaving only one primary around and in between: Santa Rosa-Tagaytay or Route 420. By the way, there's even a proposed expressway from Tanauan to Tagaytay, but I'm not convinced. Not even Dasma-Palico-Balayan-Batangas City. Now, can we settle with most numbered routes west of STAR and south of Governor's Drive be primary?

Just why I asked about why you use BrE spelling is because of one guy also from Dasma that got into it and sounded trying hard. I understand now.

I'm about to do this along with the downgrade of Dasma-Tagaytay-Lemery-Batangas City per my multiple counterarguments, but you did it.

Understandable. And yes, Dasma could beat Manila because it's home to PCU and DLSU satellite campus, but you can't deny it's part of the Manila's southern sprawl now. Didn't read my argument against trunk in case Diokno gets closed and you get two detour that you'll might avoid (via Palico and Balayan and via Talisay on the Ligaya Drive "bitukang manok")? I'm already on an edit to downgrade to primary basing on my counterarguments.

(Why use Brit spelling? Trying hard, lol)

The problem is, Lemery and Taal are both medium-sized towns (let's wait years). I'll insist on leaving JP Laurel plus connection to Batangas Pier as the only trunk in Batangas. Tagaytay is a popular getaway, but we don't account that for determining trunk network (trunks link major cities, and Tagaytay isn't among of these as of 2020). Maybe by 5 years, Silang may become city and Tagaytay reaches 100k mark on population, but we should still be careful determining trunks as Cavite pretty dense.

You may treat suburban Cavite as its own conurbation, but it's still part of the sprawl south of Manila, let alone northwest Laguna.

I support that. A primary across the province should be enough, and yes, best route between Olongapo and Dagupan is via Pampanga and Tarlac. That has been one edit I'm considering.

Going back, Route 306 got trunk because it was the main transportation backbone across Zambales, but this is based on a scheme that has the major shortfall of the being more or less obviously Manila-centric; primary being worst offender as you would force such high a class even in a sparsely populated area, with the end result of few to no secondaries around and in between.

To answer why C-4, Road 10 and Roxas Boulevard got trunk is not just to bypass the center of Manila, but also consideration to those who are diligent and use the static map to determine their route (a routing via nav app would lead you through congested city proper and you would like to avoid such route choice). Same also goes with EDSA (in addition to its expressway-like construction, though its much like the metro's larger thoroughfares). The same goes why trunk has been set to Quirino, Diego Cera and Alabang-Zapote in the south (using a nav app with avoid toll option from Magallanes or EDSA-Roxas Boulevard to Alabang, the best route may take you to East Service Road, but except FTI to Nichols, it's narrow and congested and aren't designed for through traffic.)

Back on the Dasma-Batangas City route, I can apply the same reasoning as with the Manila trunk routings, primarily the consideration for those looking up the static map in conjunction with the scenario when Diokno Highway gets closed due to landslide (as like what happened 2016). When Diokno gets closed, an alternative would be via Nasugbu and Balayan, but that would be a longer journey. Another alternative under the Diokno closure scenario is via Talisay and Tanauan, but you might want to avoid steep grade in the Ligaya Drive "bitukang manok", so you might want to travel via Laguna, the path or least resistance.

We can temporarily move the trunk back to via Pagbilao Poblacion as one mapper just updated its eastern leg that is still under construction as of December 2021, but for the rest, they can be reverted as these clearly superseded the older Poblacion routings of Maharlika Highway even though they would involve abrupt turn.

On the bypass of JP Laurel in Lipa, that can get primary at most. Its ultimate purpose is to bypass congested JP Laurel at Marawoy, it looks more like a bypass to those coming from either Balete Road and JP Laurel (and vice versa, whether headed for STAR, Balete, LIMA or Lipa Downtown).

Answering your latest reply, I would still disagree with a Dasma-Batangas trunk via Tagaytay and Lemery with the jog being very obvious at closer zoom. I can discount the comparisons with Maharlika Highway and Andaya across Camarines Norte and CamSur as these are across fairly sparse areas (and both routes are equally important). Denser areas such as CALABARZON and Manila are to be handled differently than most of rural Philippines in terms of road classification.

For Kennon Road or any similar roads, it may matter if it's used by heavy vehicles as trunk should indicate a critical link, but there are factors that support trunk for it:

- It's the shortest and most direct route to Baguio from the south
- It minimizes change of route number
- It is still the critical link to Baguio, considering the ban on trucks and buses there is temporary considering a a plan to rehabilitate it by realigning some segments (tunneling?) and replacing weak bridges.

For the Dasma-Batangas City via Tagaytay and Lemery, it's the main route for those from Dasma, but north of there, the main toll-free route is open for question. And yes, Diokno being landslide-prone also makes its questionable, in addition to involving jogs as one turns to it from Route 436 in the Lemery end or Tagaytay-Nasugbu on the Nasugbu/Calaca end.

I would have to agree with this, Santo Tomas poblacion main roads being largely secondary and isn't much important as the newer Route 4 alignment. Will follow this up with downgrade to Governor Malvar to tertiary

Except Pagbilao bypass, just leave those bypass roads alone.

Understandable (toll-free option on Magic Earth the same), but still far from ideal. Also, this just left one primary between Lipa and Santa Teresita. Trunk via Diokno also not good option because it might get closed due to landslide.

I'll be opposed to retaining Halsema as trunk. Ideally, that forms the shortest route between Baguio and Tuguegarao from the map, but that's not the case of the ground (that goes to Route 110. Also questionable if there's going to be closure due to landslide.

Concurrently, I also oppose keeping the existing primary network as they mostly serve small towns in a largely sparsely populated area. Cordillera already lacks rural secondaries (many of the primaries better fall under that class).

Fine with the downgrades along coastal Cavite, but not the upgrade to Diokno and Route 436 (not ideal trunk due to jogs). Don't be rash!

Correction: should be "[Solano, Nueva Vizcaya/Santiago City] review and correct/undo Road reclassifications, move trunk to partially opened bypass
"

That's fine in a town with large enough roads, but that's not the case in most of the Philippines. Just reviewed and fixed some of these.

Just wondering why downgrade Andaya? Redundant with Maharlika Highway?

Just partially undone or fixed the classifications here. Why would you upgrade lots of road to secondary? I noticed this and related edits lately.

I can't understand clearly what you want to say, but again, do away with your habit here to map every closure. You're saying SRIT-Davao is closed until further notice, which is not clear, and in short, unpredictable. I'm OK with a long-term closure with known end date, e.g. road under reconstruction, though it may not always be the case.

Reverted route deactivations (plus others you've tagged as such). Better not reflect very unpredictable route closure due to typhoon or quarantine, and those don't often get updated.
